The global variables behave exactly like the normal variables. They can be set with =, their content is accessed via [].

They are valid in all macros and in command mode. The following examples illustrate how to manipulate them.

1. Global variables are created with a name, a value and an associated comment.
2. This command allows to list all the global variables. Note that @ (macro return code) is defined as a global variable.
3. Delete global variables.
4. Global variables can de accessed outside macros.
